`warnings.deprecated` has no `skip_file_prefixes`

Feature or enhancement

Proposal:

Seems like when adding warnings.deprecated in https://github.com/python/cpython/pull/104004, it was forgotten to add one of the two stack skipping arguments.

It needs it for the same reasons why it already got stacklevel, e.g. because adding decorators adds stack levels in a hard to predict way (e.g. a 3rd party decorator might start calling the wrapped function one level deeper, suddenly changing where the warning points)

Has this already been discussed elsewhere?

Yes, and it was accepted, but then apparently fogotten, see link below

检查 warnings.deprecated 的实现和测试，首先了解 stacklevel 的处理方式，以及 skip_file_prefixes 在其他地方的表示方式。链接的 PR gh-156937 是当前需要检查的工作。完成的标准是 warnings.deprecated 支持针对所述 decorator 和 stack-trace 情况的 skip_file_prefixes，并且有测试覆盖该行为。
